Default Lift Height Measurements

I also own a sports car, and on one of our forums, they had a thread where people posted the actual drop of their car, measured from the center of the hub to fender. So it got me thinking, why don't we do the same here to measure our lifts? There are a lot of people putting lifts on lately, and it might be a good resource for everyone to have in one post.

So, when you get a chance, please measure the distance from the center of your hub to the bottom of your fender, front and rear. Even if you've only put on a leveling kit, measure front and rear. DO NOT measure from the ground. And just as importantly, post your lift kit and tire/wheel size.

Sadly, I'm at work thinking of this, so I can't post what I have just yet. I will when I get home.

P.S. If this has already been done, my apologies, but I'm assuming we could use an updated one.

I have a question for you....so you have the fabtech 6" lift and you added a 1" spacer in the rear and after market keys to the front to lift it up more. Any issues at all with driveline angles, vibration, etc, etc.?

I have the fabtech with 38's, and would like to get a bit more out of it, if It wont affect anything else.

let me know, thanks

I've had it this way for about 3 years without any issues. Honestly though, it almost a little too tall for 38's. I only did it to ensure that I wouldn't have any rubbing issues when I went from 37's to 38's. I changed wheels at the same time to a better offset, so I'm not sure which helped with rubbing the most, but I've never had any rubbing since I went taller.

yeah, im thinking about 40's sometime in the near future, the extra lift would set it off nicely. I have zero rubbing with my 38x15.5x18's as it sits now.

Default Re: Lift Height Measurements

I actually still have room to adjust the front higher. When I got it back from the shop, they had it sitting a little nose-high. I brought it back down, but there is room to go back up some.

The shop I dealt with is VERY well respected here in Orlando, and they actually advised against 40's. Said it was too much for the IFS. But if you upgrade your steering components, I'm thinking it should be fine. Problem is, it's hard to gear your truck correctly. I have 38's with 4.88 gears, and my speedo is almost perfect. More importantly, though, is that my powerband is still good. And keep in mind that most programmers don't go up to a 40" tire size.

Hmm, thats something to think about on the 40's. I currently do not have my truck regeared for the 38's, doesnt bother me usually, but I did notice some times that it couldnt seem to find the right gear when coming back from vacation (hills, etc).

Mine is actually sitting a little nose down at the moment. I gotta have it raised up about an inch in the front. Im waiting to get my upgraded tie rods put on, I will have them raise the front back up and realign at that point.

At first I didn't think the gears made a big difference. After driving it some more, they quickly became one of the top 3 mods I made to the truck. HUGE difference on hills. Even my gf could notice from the passenger seat.

Default Re: Lift Height Measurements

I wanted to revive this thread as there seems to be a lot of people, myself included, that are considering more lift or bigger tires. So anyone with a tape measure, please contribute.

Default Re: Lift Height Measurements

Its kinda difficult to measure from the center of the hub to the fender when you have wheel offsets that come out a few inches. I just added the cognito UCA and steering parts today and cranked upt he torsion bars, so my front is nice and even now. I think IM about to get the 1.5" spring spacer and green keys to take it up a bit more. With the cognito UCA's the ball joint angle looks like it will be fine, and the front axles look like they will be good to go as well. I will measure it up after I get these things on it in a few days or so.

Thanks for your input. And I'm sure you can get pretty close by just eyeballing. I just want to get an estimate. A quarter of an inch doesn't matter as much on trucks as it would on sports cars.

Yeah, I guess your right. Im such a freak about these kinds of things. I was a measuring fool today cranking the torsion bars, trying to get them spot on.

You should have seen me when I was adjusting the coilovers on my Twin turbo Lexus.....it was rediculous!

I will measure the H2 tomorrow, then again when I get the spacers and keys in.

Charles, why do you have the front higher than the rear out of curiosity?

Default Re: Lift Height Measurements

Remember, we're measuring to the top of the fenders. The fenders are cut higher in the front. Most cars/trucks have more fender clearance in the front.

If you wanted to measure from the ground, you'd have to pick a point on the truck that is the same front and rear. The closest thing would be that indentation in the doors, but even that doesn't go far enough forward and backward. And, if someone's driveway as off a bit, measurements would be ALL over the place.

Ya know, this is such an obvious thing, but I didnt even think about that when I was adjusting my torsion bars yesterday. Im gonna have to measure again from somewhere on the frame.

I did that before with a 4Runner I had. Drove me nuts because I kept thinking everything was off.

Default Re: Lift Height Measurements

28" Front
29" Rear

These are approximate measurements, but close enough

Keys up front and custom spacers in the rear.
